Dr. Donohue: Celebrex remains controversial med for some

Dear Drs. Donohue and Roach: I have arthritis in both knees and have taken Celebrex for years for it. I am unsure how long I should keep taking it. What is your opinion of Celebrex? Also, could stem cells ever be used for joints? — L.H.

Celebrex is in a class of medicines called COX-2 inhibitors. It is usually used for arthritis, and was specifically intended to reduce the likelihood of gastrointestinal complications, especially bleeding from the stomach. It probably has less risk of bleeding and ulcer than other arthritis medicines, but serious bleeding can still occur.

There remains some controversy about whether Celebrex increases the risk of heart disease the way another COX-2 inhibitor, Vioxx (since removed from the market), was found to in studies. Preliminary evidence suggests it is not more dangerous to the heart than other drugs, but a study is ongoing to determine this with greater certainty.

Celebrex is very useful for many people, and if you have been taking it for years with good results and no side effects that you notice, I would recommend you continue to take it.

Stem cells may indeed be useful for arthritis in the near future. Since one of the major problems in arthritis is loss of the cartilage in the joint, it makes sense to use new cells to regenerate it. But more research is needed.

Dear Dr. Donohue: In a column, you commented that the vegetable drink V8 has a fairly large amount of sodium. The regular type has 290 mg per 5.5-ounce can. However, there also is a low-sodium V8 product that has only 95 mg of sodium. I have always found it available wherever the regular V8 is sold. — W.W.

Thank you. I appreciate the information, lovers of V8 appreciate it and the manufacturer of the product greatly appreciates it.
